Abstract

A z-shape guide track surface crawler core iron used for rubber pedrail, which has an anti-wear layer in the central part, a location guide angle, a rib and a mucosity adding groove The utility model is mainly characterized in that the upper surface of the guide track is Z-shaped and the lower surface of the guide track is disposed reversely, the vertical projection of the ends of the adjacent guide track surface overlap each other so as to ensure the thrust wheels locate always at the guide track surface and avoid the thrust wheels to get into the clearance. and therefore overcomes the shortcoming of the existing techniques that the axial swing caused by the thrust wheels which get into the clearance and the vibration and the noise brought about by the axial swing, at the same time, meet the request that the pedrail has a smaller bending radius so as to make the machine be more compact.

Description

Zigzag guide pass crawler belt core iron

Affiliated technical field

The utility model belongs to self-propelled vehicle, trailer group in International Patent Classification (IPC), i.e. B62D, particularly core for rubber track, i.e. B62D55/20.

Background technology

At present both at home and abroad core for rubber track is made by metal forging or casting, be to satisfy drive, with the bonding and guide rail effect of steel curtain.When high-power transmission, very easily string is moving between traditional core iron, and guide pass and drive surface be than quick-wearing, thereby has changed meshing performance.The tradition core iron also easily breaks away from the steel curtain, makes the power transmission inefficacy of crawler belt, and the flexural deformation of bottom wing on the core iron.

No. 200520115985.9 patent application technology of our company have overcome above-mentioned shortcoming substantially.But owing between the adjacent core iron guide pass bigger gap is arranged, so caterpillar wheel is absorbed in this gap and axial wobble easily.

The utility model content

The purpose of this utility model provides a kind of rubber belt track zigzag guide pass crawler belt core iron.

It can not only be avoided, and string moves between core iron, has prolonged the life-span, is more suitable for the rubber belt track of high-power transmission, and can avoids the axial wobble of caterpillar wheel.

It is as follows to disclose new technical scheme:

A kind of zigzag guide pass crawler belt core iron, there is prominent muscle in the front of both wing portions up and down, there is the tackify groove at the back side, there is upper and lower guide rail in front between alar part and the central part, there is laterally zygomorphic positioning and guiding angle at the back side, the drive surface of said guide pass up and down and central part has wearing course, is characterised in that the upper rail face is zigzag, the zigzag reversed arrangement of lower guideway face; The end of the adjacent core iron guide pass in the left and right sides is superimposed mutually in the projection of vertical direction.

On probation according to the sample warp that this scheme is made, not only can be fit to the requirement of high-power transmission, and overcome the machine caterpillar wheel and be absorbed in the guide pass gap and the drawback of axial wobble, thereby machine run is steady, noise is little, and is not easy to wear, prolonged the life-span greatlyyer, can also satisfy the more requirement of small-bend radius of crawler belt, make more compact structure.Being more suitable for relatively large construction machinery and equipment uses.

Positioning and guiding angle and tackify groove patent applied for are regarded prior art here as, have among the figure slightly.

The specific embodiment

The zigzag guide pass crawler belt core iron 1 that a kind of rubber belt track is used, there is prominent muscle 2 in the front of both wing portions up and down, and there is the tackify groove at the back side.There is upper and lower guide rail in front between alar part and the central part, there is laterally zygomorphic positioning and guiding angle at the back side, and the drive surface of said guide pass 4 up and down and central part has wearing course, and said upper rail face 4 is zigzag, the zigzag reversed arrangement of lower guideway face 4 promptly spins upside down coincidence; The end of left and right adjacent core iron guide pass is superimposed mutually in the projection of vertical direction.The caterpillar wheel 3 of machine steadily rolls on guide pass 4 all the time like this, has overcome the drawback that machine vibration is big, noise is big of axially waving and bringing that caterpillar wheel in the prior art is absorbed in the gap.

Claims

A kind of zigzag guide pass crawler belt core iron (1), there is prominent muscle (2) in the front of both wing portions up and down, there is the tackify groove at the back side, there is upper and lower guide rail in front between alar part and the central part, there is laterally zygomorphic positioning and guiding angle at the back side, the drive surface of said guide pass (4) up and down and central part has wearing course, and it is characterized in that: said upper rail face (4) is zigzag, the zigzag reversed arrangement of lower guideway face (4); The end of left and right adjacent core iron guide pass is superimposed mutually in the projection of vertical direction.
